Is there a way to ensure proper pulley alignment?
I have a 302 in my 69 mustang, and about two years ago I had a local custom shop install a vintage air setup (yeah, I know I'm weak, but I'm in Texas!). Since then, I have thrown the new AC belt several times. To my eye, I don't think the pulleys line up correctly. All the brackets are custom so there is no way to be certain that they are lined up, like you would expect in a factory install. Is there a scientific way (other than eyballing it) to make sure your belts pulleys line up on a custom engine build? I do not want to pop for a serpentine system since I will presumably still have the problem of making sure all the pulleys line up on the custom engine/AC setup.
